Dogs can’t because they present a danger to humans. That’s the clear difference.
I’m not just being difficult. My wife was a trainer at the human society for years. We know the stuff and have tried to do it. I value my cat more then wild birds and rodents, and my wife does taxidermy for whatever she brings back.
My cat broke her first harness, slipped out of her second, and now she flails whenever we try to come near her with a harness. We’ve tried walking, but she refuses to move. You don’t know my cat, and you don’t seem to realize that this won’t make her happy.
Local ecosystem destruction is a moot argument because we had multiple feral cats in our yard every night when we moved in, and now we have none. We have fewer cats total in our yard.
At the end of the day, she’s 14 and will start slowing down soon. If she dies, she lived a great life. My last outdoor cat was 20 years old. I get long living cats who are happy by just letting them be cats.
